I have a lot of data on this. I'm not guessing here and I have no agenda to push. I submit to whoever is going to make me the most money when grading cards to sell. Which means I submit to both PSA and SGC, depending on the card.

You cannot just look at 10 random PSA 6 copies of a card and compare them with 10 random SGC 6 copies of the same card and make the claim that PSA brings higher prices than SGC because those PSA 6s outsold the SGC 6s. Not with vintage. You can't even make that claim across 100 copies of each, or even 100 copies each of 1,000 different cards. That was my entire point in creating that thread. If you want to answer the question of which TPG sells for more, PSA or SGC, then you have to take THE SAME CARD and send it to both PSA and SGC and only then can you determine which one outsells the other. Then you have to specify which cards you're talking about; post-war vintage commons, vintage HOFers with soft corners, OC cards, ultra-modern, etc. It all matters, and you're leaving money on the table if you haven't figured that out yet.

If I have a card that I know will get a 4 at both PSA and SGC, like an otherwise EX-MT card with a tiny surface wrinkle, then I'm sending it to PSA because yes, in that case, it will sell for more as a PSA 4. But If I have a dead-centered 1954 Topps Hank Aaron RC with slightly soft corners and a flawless surface, I'd be making a financial blunder by sending it to PSA because SGC is going to give that card a higher grade nearly every single time.

HOF'ers the gap is smaller, commons the gap is HUGE at the higher grades, easily explainable by the lack of a set registry.

Yes, for commons, the gap is much more significant. Particularly at the higher grades. Even a PSA 8 will often compete with an SGC 9 for some random 1970s Topps common.
